Tool/software:
Hello!
I haven't been able to find any explicit power-on or power-down sequencing requirements for the ADS7953 in the datasheet. The "Recommended Operating Conditions" specify +VBD should be less than +VA, but the Absolute Max Ratings don't specify any dependency between +VBD and +VA. Is it safe to power on +VBD before +VA is powered?
For reference - in our application:
+VBD is 1.8V and powers on first
+VA is 3.3V and powers on <5ms after +VBD
VREF is 2.048V and will power up simultaneously with +VA
